Positive Pressure User Seal CheckUsing Disc FiltersRemove the exhalation valve cover. Place the palm of your hand over the exhalation valve and exhale gently. If the facepiece bulges slightly and no air leaks are detected between the face and the facepiece, a proper seal check has been

obtained. If faceseal air leakage is detected, reposition the respirator on your face and/or readjust the tension of the straps to eliminate leakage and recheck seal. Replace exhalation valve cover.

Using CartridgesPlace the palms of your hands over the cartridges and inhale gently. The facepiece should collapse slightly. If air leaks between the face and the faceseal of the respirator, reposition it and adjust the straps for a tighter seal. If you cannot achieve a proper

seal, do not enter the contaminated area. See your supervisor.
